Mechanical Face Seals

Mechanical Face Seals are a special form of mechanical seals. They are also known under other designations, such as lifetime seals, floating seals, duo cone seals, toric seals and heavy duty seals.

There are two different types of Mechanical Face Seals:

  • Type DO is the most common form that uses an O-Ring as a secondary sealing element.
  • Type DF has an elastomer with a diamond-shaped cross section as a secondary sealing element instead of the O-Ring.
